主要特点 PR121/P E3H32

运行无需外部电源：可以独立运行，不需要额外的外部电源支持其基本的保护功能等操作。

采用微处理器技术：通过微处理器实现对各种参数的·准监测和控制，从而达到较好的保护效果。

精密度高：在对电流等参数的监测、判断以及保护动作方面，具有较高的精密度。

对电流真实值R.M.S反应灵敏：能够快速、准确地对电流的实际有效值做出反应，以便及时进行保护动作。

故障原因指示以及脱扣数据记录：当发生故障导致脱扣后，可以指示故障原因，并且记录脱扣相关的数据，方便故障排查和分析。

各型号脱扣器可互换：这一特性为产品的维护、更换以及升级等操作提供了便利。

可遥控操作：可以对断路器进行遥控操作，例如分闸、合闸、报警复位等操作均能被发送到断路器和保护脱扣器上。不过合闸指令仅仅在安·检查后才能执行（如在脱扣器上，没有激活的诊断报警）。还可以通过通讯总线来对保护脱扣器进行遥控设定。

Main features

No external power supply required for operation: It can operate independently and does not require additional external power supply to support its basic protection functions and other operations.

Adopt microprocessor technology: Accurate monitoring and control of various parameters are achieved through microprocessors, thereby achieving better protection effects.

High precision: It has high precision in monitoring, judging and protecting actions of current and other parameters.

Sensitive response to the actual current value R.M.S: It can respond quickly and accurately to the actual effective value of the current in order to carry out timely protection actions.

Fault cause indication and tripping data recording: When a fault occurs and causes a trip, the fault cause can be indicated and trip-related data recorded to facilitate troubleshooting and analysis.

Each type of trip unit is interchangeable: this feature provides convenience for product maintenance, replacement and upgrade operations.

Remote control operation: The circuit breaker can be operated remotely, such as opening, closing, alarm reset and other operations can be sent to the circuit breaker and protection tripper. However, the closing command can only be executed after a safety check (eg on the trip unit, no diagnostic alarm is active). The protection tripper can also be set remotely through the communication bus.
